Specification of Letters Patent.

- Patented May 26, 1914.

Application filed August 12, 1908. Serial No. 448,165.

' To all whom it may concern .1

is required that the Be it known that I, Ln BARON O. COLT, of Bristol, in the county of Bristol and State of Rhode Island, have invented certain new and useful Improvements in Sole-Rolling Machines; and I do hereby declare the following specification, taken in connection with the accompanying drawings, forming a part of the same, to be a full, clear, and exact description thereof.

The invention relates to a machine which is more particularly adapted for use in connection with the manufacture of rubber shoes or shoes composed of rubber and fabric. In the manufacture of such shoes it several soles applied thereto, including the out-sole, shall be rolled into firm and close contact with the part or parts immediately beneath the same. In the case of the out-sole it is necessary or desirable not only that the main body of the sole shall thus be rolled, but also that the edge or edges of the sole shallibe rolled over and on to the adjacent upper. Heretofore the operation of thus rolling on the outsole has been performed entirely by hand, such rolling operation being performed by the operator by means of a hand-roller.

' able bed adapted to receive a The object of the present invention is to provide a machine which will serve to automatically effect the requisite rolling of an out-sole upon the lasted shoe and thereby dispense with the operation of hand rolling. To that end the invention consists primarily in the combination, with a movable bed adapted to receive a lasted shoe, of a series of pressure-rollers arranged and adapted to act successively upon the lasted shoe and roll the out-sole thereon as said lasted shoe is carried by said movable bed past said pressure-rollers.

The invent-ion further consists in the combination, with a series of pressure-rollers, of a movable bed adapted to receive a series of lasted shoes and carry the same successively past said pressure-rollers, whereby each of said pressure-rollers may simultaneously act upon a lasted shoe.

The invention further consists in the combination, with a pressure-roller, of a movlasted shoe, and means for varying the position of the lasted shoe with relation to the pressureroller as said shoe is carried along by the movable bed.

The invention further consists in the combination, with a series of pressure-rollers, of a movable bed adapted to receive a series of lasted shoes and carry the same successively past said pressure-rollers, and means for varying the position of each lasted shoe as it travelsalong with relation to the successive pressure-rollers.

The invention further consists in certain comblnations and arrangements of parts to be hereinafter described and claimed.

Referring to the drawings, Figure 1 is a side elevation ofthe machine embodying the lnyentlon. Fig. 2 is an end view thereof. Flg. is a section on the line mw of Fig. 1. Flg. 4 is a section on the line yy of Fig. 1. Fig. 5 is a section on the line zz of Fig. 1.

The machine comprises a suitable frame composed of a series of uprights 1, 1, rigidly connected together. As shown in the drawlngs, said uprights are connected at top and bottom by bars or rails 2, 2, preferably extending the entire length of the machine, and which bars or rails constitute a track for the movable bed o-n which the lasted uppers are mounted.

Mounted in suitable bearings at or near one end of the machine is a driving shaft 3 which may be provided with tight and loose pulleys 4 and 5. Secured to said shaft 3 are two sprocket-wheels 6, 6, and mounted in suitable bearings at the opposite end of the machine is a shaft 7 to which is secured I which extends around and is engaged bythe.

sprocket-wheels 6 and 8.

As shown in the drawings, the movable bed or endless conveyer 9 comprises a series of carriages 10,'each adapted to carry a lasted upper. Each of said carriages comprises two side bars 11, 11, and two end bars 12, 12, connecting the side bars together, as shown in Fig. 2. Mounted in the projecting ends of the side bars are two axles 13, 13, provided with wheels 14 adapted to runon'the track formed by the connecting bars or rails 2, 2, said wheels being preferably flanged as shown. Extending between and secured to the end bars 12 is a bar or rod 15 on which is pivoted a rocking or swinging frame or support 16. Said swinging frame or support is provided with 1 with suitable pins 19 to engage the usual holes in the last. The adjacent carriages 10 are connected together by suitable links 20, one on each side. The wheels 14 also constitute means by which engagement of the movable bed or endless conveyer with the sprocket-wheels 6 and 8 is made, said wheels engaging suitable forks 21 formed on said sprocket-wheels.

For the purpose of guiding or controlling the positions of the several swinging frames or supports 16 an endless cam-path 22 is provided. As shown in the drawings, this cam-path is formed by means of two parallel rods 23, said rods being mounted in or supported by suitable brackets 24 secured to the uprights 1. As shown in the drawings, the rods 23 are spaced to receive between them the guiding-roller 18 on the arm 17 projecting from the swinging frame or support 16. Throughout the greater portion of their length the two rods 23, 23, are not only parallel, but are also in the same horizontal plane, but at the points 23 and 23 said rods are turned so as to stand in diagonal planes, one of said diagonal planes being substantially at right angles to the other, as shown in Figs. 4 and 5.

Rigidly secured to the upper bars 2 are a series of arms or brackets 25. Pivoted to the upper ends of said arms is a U-shaped frame 26, the cross-piece of which is provided with two projections 27 forming bearings in which the axle of the pressure-roller 28 is mounted. Secured on the cross-piece of the frame 26 is a suitable pressure-weight 29. In order to arrest or limit the downward movement of the U-shapedframe carrying the operating roll, two supports 30, 30, are provided, one on each side of the machine, said supports being in line with and adapted to engage projections 31 on the side bars of the U-shaped frame. Preferably the supports 30 are in the form of spiral springs, as shown in the drawings.

32, 32 82 and 32 represent a series of lasted shoes in position on the movable bed or endless belt 9.

In the drawings three pressure-rollers are shown which for convenience are designated, respectively, 28, 28 and 28 The roller 28 is arranged and adapted to roll the face of the out-sole, while the roller 28 is adapted to roll one edge of the sole, and the roller 28 is adapted to roll the opposite edge, all as shown in Figs. 1, 3, 1, and 5. Preferably the rollers 28 and 28', instead of being arranged horizontally, are arranged angularly, one at one angle and the other at another, as shown in Figs. 4 and 5.

The operation of the machine above described is as follows: It being understood that the movable bed or endless conveyer 9 is continuously moving, the operator places a. lasted shoe with the out-sole applied thereto on each of the carriages 1O successively as they come along in advance of the pressure-roller 28. As said movable bed travels along, the toe of the lasted shoe, as for example the shoe 32 in the drawings, will be brought into engagement with the under side of said pressure-roller 28, which roller will, as the lasted shoe is carried thereunder, be pressed against the out-sole by the action of the weight 29 and will operate to roll the out-sole ,into close contact with the clothfilling sole or other part beneath the same. As the movable bed travels along, the shoe thus acted upon by the pressure-roller 28 will be brought to the position of the shoe 32 in the drawings and where it will be acted upon by the pressure-roller 28. the shoe is thus moved from one position to the other by the travel of the movable bed, the swinging frame or support 16 and the shoe carried thereby will be rocked or tilted by the engagement of the roller 18 with the angular cam-path into the posit-ion shown in Fig. 4E, and so that the roller 28 will act upon one edge of the shoe and roll the same into close contact with the upper. When the shoe has thus been acted upon by the pressure-roller 28 it is brought by the continued travel of the movable bed into the position of the shoe 32 in the drawings, and where it will be acted upon by the pressure-roller 28*. In thus traveling from the position 32 to the position 32 the swinging frame or support 16 with the lasted shoe thereon will by the reversed angular cam-path be rocked or tilted in the opposite direction, and so that the opposite edge of the shoe will be acted upon by said roller 28, as shown in Fig. 5. When the lasted shoe has passed from beneath the roller 28 the downward movement of said roller will be arrested by the engagement of the projections 31 with the supports or spring 30 in a position where the toe of the next lasted shoe to be brought along by the movable bed will engage said pressure-roller below the axis thereof, and so that by the continued move} ment of said next lasted shoe the roller will be suficiently lifted to pass beneath the same, the roller acting thereon with a pressure due to the weight 29 referred to. It will be understood that each of the pressure-rollers is similarly arrested by its spring or support '30 when the lasted shoe has passed from beneath said roller.

As will be seen, the rolling of the sole upon the shoe in the machine above described is effected by the joint action or cooperation of each pressure-roller and the movable bed,

said movable bed serving to carry the lasted shoe beneath said pressure-roller and to cause said pressure-roller to act upon the sole from one end of the shoe to the other as the shoe is carried thereunder. It will be further seen that by mounting the lasted shoe on a rocking or tilting frame or support, and by providing means for rocking or tilting said frame, first in one direction andthen in the other, the edges, as'well as the face, of the sole, may be rolled,first one edge and then the other. It will be further seen that with a machineconstructed as shown and described, and 'inwhich three pressure-rollers are employed, three lasted uppers may be simultaneously operated upon, the face of the out-sole being rolled on one shoe by the roller 28; while one edge .of'the sole is being rolled on another shoe bylthe roller 28*, and the edge of the sole on still another shoe is being rolled by the roller 28". p c

As Will be seen, the operation of rolling on the out-sole in the machine shown and described is performed entirely automatically and without any hand operation or inter-- vention, it being necessary for the operator simply to place-the lasted shoes, one after the other, on to the successive carriages as they come along and to remove the lasted shoes from said carriages after the soles vhave been rolled thereon.
